Abstract: The complex,[Zn(C28 H20 N4 O2)(CH3 OH)]was synthesized and characterized by elemental analysis and IR spectroscopy. The single crystal structure analysis shows that the complex exhibits a single-stranded helix with the Zn (Ⅱ) atom having a distorted trigonal bipyramidal configuration.Edge-to-face and edge-to-edge π…π stacking interactions and C-H…π interactions between the aromatic rings and O-H…O hydrogen bonds lead to a three-dimensional network in the crystal structure. Crystal data for the complex: triclinic, space group P(1-)with a =0.9303(2)nm,b = 1. 0413(2) nm,c = 1. 4625 (3)nm,α=96.340(10)°,β=103.160(10)°,γ=112. 500(10)°,V = 1.2434(4)nm3,Z =2,dc=1.447g·cm-3 ,T=293(2)K,μ=1.027mm-1.F(000)=560,R1=0.0463,wR2=0.0941[I＞2σ(I)].
